Open Correction
The open correction feature of the E4980A/AL compensates for any stray
admittances (G, B) that may exist within the interval from the calibration plane,
which is determined by the selected cable length, to the DUT connecting
points (see Figure 4-9).

Description of Correction Based on All Frequency Points
In this correction method, open correction data are collected from all 51
predetermined frequency points, regardless of the test frequency settings. At
the other frequency points, correction is done using data calculated by
interpolating the data collected at the 51 points (see Figure 4-10). The
following tables list the 51 predetermined frequency points:
